How to fix a broken motor in car

a good selection of engine oil to the car

Repair the car after the accident must be preceded by an accurate determination of cause resulting incident, otherwise the driver will be exposed to the fact that after some time again cause a car accident because of this that drives a defective car. The reason for the resulting failure can be either a technical defect, for which the driver is not responsible and long-term use of motor oils of poor quality. Therefore, when car repair is done, exchange the damaged parts, and selects a good engine oil, the driver should now use. Allowing the car to re-use will be made only after a thorough verification of the state of the already made repairs.

The problem of finding car parts

If we have a very rare car certainly our car can be the object of envy from friends, family or even strangers. Often, however, it can happen that a limited edition produced cars very hard to find the right car parts. Currently the easiest special parts can be found for example on the Internet, due to the fact that recently there are extremely many sites advertising of this kind offers. The problem may also occur with the installation of such parts, because not every mechanic to take orders for all cars. Such problems are best to consider when choosing a car already.

Some simpler designs

In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings), and rods connecting the pistons to the crankshaft. The oil collects in an oil pan, or sump, at the bottom of the crankcase. In some small engines such as lawn mower engines, dippers on the bottoms of connecting rods dip into the oil at the bottom and splash it around the crankcase as needed to lubricate parts inside. In modern vehicle engines, the oil pump takes oil from the oil pan and sends it through the oil filter into oil galleries, from which the oil lubricates the main bearings holding the crankshaft up at the main journals and camshaft bearings operating the valves. In typical modern vehicles, oil pressure-fed from the oil galleries to the main bearings enters holes in the main journals of the crankshaft. From these holes in the main journals, the oil moves through passageways inside the crankshaft to exit holes in the rod journals to lubricate the rod bearings and connecting rods. Some simpler designs relied on these rapidly moving parts to splash and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. However, in modern designs, there are also passageways through the rods which carry oil from the rod bearings to the rod-piston connections and lubricate the contacting surfaces between the piston rings and interior surfaces of the cylinders. This oil film also serves as a seal between the piston rings and cylinder walls to separate the combustion chamber in the cylinder head from the crankcase. The oil then drips back down into the oil pan.45

Motor oil may also serve as a cooling agent. In some constructions oil is sprayed through a nozzle inside the crankcase onto the piston to provide cooling of specific parts that undergo high temperature strain. On the other hand, the thermal capacity of the oil pool has to be filled, i.e. the oil has to reach its designed temperature range before it can protect the engine under high load. This typically takes longer than heating the main cooling agent ? water or mixtures thereof ? up to its operating temperature. In order to inform the driver about the oil temperature, some older and most high performance or racing engines feature an oil thermometer.

Due to its high viscosity, motor oil is not always the preferred oil for certain applications. Some applications make use of lighter products such as WD-40, when a lighter oil is desired, or honing oil if the desired viscosity needs to be mid-range.6
